From Entangled Top Quarks to Detector Instrumentation

Collider physics is transitioning from measurements of rates to measurements of quantum structure. I will present a program that integrates quantum-information observables, detector systems, and AI-driven inference to exploit this shift at the LHC. The recent observation of quantum entanglement in top–antitop production demonstrates that collider experiments can access the quantum state of fundamental interactions. This enables quantum tomography at the energy frontier, with sensitivity to subtle Standard Model dynamics, including threshold effects in top-quark production where short-distance QCD quasi-bound states (“toponium”) become accessible. Building on this, I develop multidimensional, correlation-sensitive measurements that extend quantum tomography to precision studies of the Standard Model and beyond. Interpreting these observables exceeds the reach of traditional frameworks, motivating AI/ML-based and optimized inference strategies for regimes where complexity, rather than statistics, limits sensitivity. 

Realizing this potential in full places direct constraints on future detector design. I will highlight lightweight, thermally integrated tracking systems for the HL-LHC and future facilities, enabled by a unified detector-mechanics program. Together, this defines a single strategy: designing detectors that preserve quantum information, performing measurements that expose it, and developing inference tools capable of interpreting it. This program positions collider experiments as laboratories for quantum information science at the highestenergies.
